any reason not to update 3GS to 4.2?

[superspud]

so my lady friend just got a new 3GS (I finally convinced her!!!!) and im curious if there are any reasons not to update it to 4.2.

I love 4.2 on my iPhone 4 but when I asked the ATT guy if it already had 4.2 on her 3GS he looked at me like I was an idiot and said "you dont want 4.2 on your 3GS man, its bad news".......


i've looked around for a bit and done some searches but cant find any real negative reviews about 4.2 on a 3GS aside from the few features it left out that only the iPhone 4 got.


so MacRumors, what do you think?

4.x is awesome on my 3Gs. No need to go iP4 for me.

Its fine unless you want to JB then you might be stuck with a tethered JB.
If you plan on staying stock I dont see a reason why not to update to 4.2.1

If there're any plans to go overseas, it's also a bitch to unlock.
